(PR#7824) handling of zero and negative indices in
I've put this in (with some different wording). Although S blithely
accepts mis-dimensioned index matrices I agree this is wrong and have made
it an error.

Correction to vec-subset speed patch
I found a bug in one of the fourteen speed patches I posted, namely in
patch-vec-subset. I've fixed this (I now see one does need to
duplicate index vectors sometimes, though one can avoid it most of the
time). I also split this patch in two, since it really has two
different and independent parts. The patch-vec-subset patch now has
only some straightforward (locally-checkable) speedups for

treatment of zero and negative elements in matrix indices
Matrix indexing seems to give rather "variable" results when zeros or
negative values are included among the indices (in terms of both error
messages and in terms of the number of returned values when there is no
error message).
Is this the intended behavior?
I couldn't see any comments about zeros or negative values in matrix
indices in either ?"[" or Section 3.4.2

low-variance warning in lmer
For block effects with small variance, lmer will sometimes
estimate the variance as being very close to zero and issue
a warning. I don't have a problem with this -- I've explored
things a bit with some simulations (see below) and conclude that
this is probably inevitable when trying to incorporate
random effects with not very much data (the means and medians
of estimates are plausibly

A sapply() funny.
The sapply function is refusing to return a result for what seem to
me to be mysterious reasons. Here is a toy example:
set.seed(111)
X <- list(x=runif(20),y=runif(20))
rvec <- seq(0.01,0.15,length=42)
foo <- function(x,X,cc) {
mean((X$x)^x + (X$y)^cc)
}
bar <- function(x,a,b){a+b*x}
try.b <- sapply(rvec,bar,a=1,b=2) # This runs without a problem and

xyplot: subscripts, groups and subset
Hi,
I'm running the following code to produce lattice plots of microfibril
angle versus ring number in Scots pine. There are 12 trees and 5 sample
positions ("Position") in each tree:

about the subscript assignment porblem
Hi, Dear,
I have a problem for the new version 2.0 of R
When I put this code in it give me the error:
uis$ivhx3[uis$ivhx>0] <- 1*(uis$ivhx==3)
Error: NAs are not allowed in subscripted assignments
but this would happen in version 1.91
there are missing data in the data set and it is
represented as NA
the data set can be find on line

Asterisk -> Nortel CS1K via NRS
Hi,
Was wondering if anyone had any tips or experience in getting a Nortel CS1K
and Asterisk 1.4.19 to talk to each other via NRS? So far I've gotten
asterisk to place calls to the CS1k via the NRS, however calls originated by
the CS1K get rejected by the NRS with a 404 Not Found message. If I take
the NRS out of the equation by replacing the IP address of the NRS in the
CS1K with that

NetCDF output in R
Dear CSAG R users,
I will be glad if someone can point out what I am doing wrong or not doing at all in this.
I am trying to write out netcdf file in R. I have 26 time step but only the first time step is written.
For example:
>library(ncdf)
>path <- '/home/work/'
>forecast <- open.ncdf(paste(path,'cam.1980.2005.nc',sep=""))

2 bugs in max.col() (PR#9542)
Dear R-Developers,
I think I found two bugs in max.col(). Ties between zeros are not broken, which might affect simulations. -Inf and Zero can be treated the same, which can give completely wrong results, e.g. when the second max is sought by replacing all maxs by -Inf.
To fix max.col I do offer the C-code behind my function rowMax(), which also handles NAs and seems to be faster. However,

using mle2 for multinomial model optimization
Hi there
I'm trying to find the mle fo a multinomial model ->*L(N,h,S?x)*. There
is only *N* I want to estimate, which is used in the number of successes
for the last cell probability. These successes are given by:
p^(N-x1-x2-...xi)
All the other parameters (i.e. h and S) I know from somewhere else.
Here is what I've tried to do so far for a imaginary data set:

nested hierarchical design

I would like to know what syntax I need to use to do a nested anova for
1. a continuous variable and 2. count data (x out of y)

in R as well.
This is the hierarchical model I would like to use: a continuous

Move the main titel to the left of the plot
Dear R helpers
I wish to move the main title, which appears on a dotplot to be right
aligned with the left axis. Is there are parameter associated with dotplot
'main' that allows the title to be placed where I want it?
Code snippet relating to dotplot is below.
